Hi,
I tried to create a local database in Visual studio 2012. Everything works fine;however, when I try to create a windows form application (c#) and tried to add/edit/delete data I cannot do it. I keep on getting this message "unhandled exception" when i try to run the form. I searched online and there seem to be no answers so I was wondering if anyone can help me with this process. This is the video that i followed : http://www.youtube.com/watch?v=1EpYqtSlOr8. Thanks a lot.
